Connecticut vehicle registration renews every two years, and you can renew online, by mail, or in person at a DMV office

Connecticut sends you a renewal notice in the mail about 60 days before your registration expires. The notice tells you the exact expiration date, your vehicle's registration number, and the fee you owe. You have three ways to renew: online through the Connecticut DMV website (the fastest option), by mail using the renewal notice, or by visiting a DMV office in person. You do not have to renew on the expiration date — you can renew up to six months early, which some people do to avoid the rush.

The fee depends on your vehicle's weight and type. Connecticut charges a base registration fee plus a weight fee. A standard passenger car typically costs between $130 and $180 for two years, but trucks, motorcycles, and commercial vehicles have different rates. The DMV website has a fee calculator where you can enter your vehicle details and see the exact amount before you commit to renewing.

Key Takeaways

  • Connecticut registration renews every two years, and the DMV mails you a renewal notice about 60 days before expiration.
  • Online renewal through the Connecticut DMV website is the fastest method and takes about 10 minutes if you have your renewal notice and a payment method ready.
  • You can renew by mail by returning your renewal notice with a check or money order, but mail processing typically takes two to three weeks.
  • Your vehicle must pass an emissions inspection before you renew if it is subject to Connecticut's inspection program, or your renewal will be rejected.
  • If your registration has already expired, you can still renew online or by mail, but driving with an expired registration is illegal and can result in a fine.

Renewing online through the Connecticut DMV website

Online renewal is available at ct.gov/dmv under the "Vehicle Services" section. You will need your renewal notice (which has your registration number), your vehicle identification number (VIN), and a valid payment method — credit card, debit card, or electronic check. The process takes about 10 minutes. After you submit payment, the DMV sends you a confirmation email with your new registration number and a temporary registration document you can print.

Your physical registration card arrives in the mail within 7 to 10 business days. During that time, keep the printed confirmation with you in the vehicle as proof of renewal. Online renewal is open 24 hours a day, seven days a week, so you can renew at any time that works for you — you do not have to visit an office or wait for business hours.

Renewing by mail

If you prefer to renew by mail, use the renewal notice the DMV sent you. Write a check or money order for the amount shown on the notice, sign the back of the notice, and mail both to the address printed on the form. Include a copy of your vehicle's current registration card if you have it. Mail your renewal to the Connecticut DMV at the address on your notice — different regions may have different processing centers.

Mail renewal typically takes two to three weeks from the time the DMV receives your envelope. If you are close to your expiration date, mail renewal cuts it close. You can track your renewal status online at ct.gov/dmv if you want to check whether the DMV has received and processed your payment. Keep a copy of your mailed renewal notice for your records in case there is a question later.

Renewing in person at a DMV office

You can renew at any Connecticut DMV office during regular business hours. Bring your renewal notice, your vehicle's current registration card, a valid photo ID, and your payment method (cash, check, debit card, or credit card). The DMV office will process your renewal on the spot, and you will receive your new registration card before you leave. This is the fastest way to get your new card in hand if you have already missed your expiration date or are renewing at the last minute.

Wait times at DMV offices vary by location and time of day. Offices are typically less busy on weekday mornings and more crowded on weekends and late afternoons. You can check current wait times on the Connecticut DMV website before you go. Some offices allow you to schedule an appointment online, which can save you time.

Emissions inspection requirements before renewal

Connecticut requires an emissions inspection for most vehicles registered in the state. Your vehicle must pass this inspection before you can renew your registration. If your inspection is expired or missing, the DMV's online system will reject your renewal request. You can get an inspection at any Connecticut emissions testing station — the DMV website lists all approved stations by town.

The inspection costs about $30 and takes 15 to 30 minutes. Bring your vehicle's current registration card and a valid photo ID. Once you pass, the testing station gives you a receipt with your inspection number. You will need this number when you renew your registration online or by mail. If your vehicle fails the inspection, you have 60 days to fix the problem and retest at no additional charge.

What happens if your registration expires

Driving with an expired registration is illegal in Connecticut. If you are pulled over, you can receive a fine of $100 to $200 depending on how long your registration has been expired. You can still renew after expiration — the process is the same, and there is no penalty fee added by the DMV. However, the longer your registration stays expired, the greater the risk of being stopped and cited.

If your registration expired more than a few months ago, renew as soon as possible. Online renewal works even if your registration is expired, so you can renew when ready without visiting an office. Your new registration will be valid for two years from the date you renew, not from the date your old one expired.

Scam alert: Fake renewal notices and phishing emails

The Connecticut DMV does not contact you by email or text message to renew your registration or ask for payment. If you receive an email or text claiming to be from the DMV and asking you to click a link or provide personal information, it is a scam. Delete it when ready and do not click any links.

Scammers also mail fake renewal notices that look similar to real ones but direct you to send payment to a private address or website. Real Connecticut DMV renewal notices come from the official DMV mailing address and direct you to ct.gov/dmv or a DMV office. If you are unsure whether a notice is real, call the Connecticut DMV at 860-263-5700 to verify before sending any money. Never pay for vehicle registration through a third-party website or service — always go directly to ct.gov/dmv or a DMV office.

Frequently Asked Questions

Can I renew my registration if my vehicle has a lien on it?

Yes. A lien does not prevent you from renewing. The lienholder's name appears on your registration card, but you can renew online, by mail, or in person using the same process as any other vehicle. The lien remains on the vehicle until it is paid off.

What if I lost my renewal notice?

You can still renew online at ct.gov/dmv without the notice — you will need your VIN and registration number instead. If you do not have those, call the Connecticut DMV at 860-263-5700 and they can look up your account and send you a replacement notice by mail.

Do I need to renew my registration if I sold my vehicle?

No. Once you sell your vehicle, you should notify the Connecticut DMV of the sale. You can do this online at ct.gov/dmv or by mail. Do not renew a registration for a vehicle you no longer own.

How long is my temporary registration valid while I wait for my card?

Your printed confirmation from online renewal is valid for 30 days. If your physical registration card does not arrive within that time, contact the Connecticut DMV. Your registration is officially active once you renew, even if the card is still in the mail.

Can I renew if my address has changed?

Yes. If you moved, update your address with the Connecticut DMV before or at the time of renewal. You can update your address online at ct.gov/dmv, by mail, or in person at a DMV office. Use your new address on your renewal so the DMV has your current contact information.
